![]() Usually, the most common way physios and patients gauge if they are progressing or not with rehab is if they feel less pain when doing an exercise or task. However, not many physios measure or record the volume or intensity of rehab for patients, and as a consequence, many are unaware if they are progressing or regressing. This gives this exercise a volume of 960 (5kg x 3 set x 8 reps x 8 RPE). So let’s say we also did some lateral shoulder raises with 5kg dumbbells, for 3 sets, and did 8 reps each time and it was also hard at 8/10 RPE. We can also add the volume of each exercise to others in a session to give us the total session volume. This gives us a total volume for this exercise of 2400. Now let’s say we found that hard an gave it a score of 8/10. This gives you a volume for this exercise of 300 (10kg x 3 sets x 10 reps). So let’s say you’re doing a 10kg dumbbell shoulder press, for 3 sets, and you do 10 reps per set. This is usually done using rate of perceived exertion (RPE) scales such as the Borg Scale ranging from 6-20 to coincide with heart rate, or the more common modified Borg scale ranging from 1-10 with 10 being maximal effort. The intensity of an exercise is an individual’s internal subjective rating of how hard or effortful an exercise feels. In its simplest form volume can be worked out for resistance exercise as the load x sets x reps or time x distance for cardio exercise. ![]() The volume of an exercise gives you a way to quantify the amount of work done. I want to highlight why these are so important for physios to consider and monitor during their patient’s rehab. In this blog, I want to discuss the two most important parameters of exercise INTENSITY and VOLUME. That’s if they bother to adjust and monitor anything at all. It still frustrates me how little most physios know about exercise, with many not knowing how to progress or regress it, or what parameters are more important to adjust and monitor.
